RVAC RMUs are fully sealed and insulated switchgears developed by ECPS exclusively for the cable system, and have been extensively applied in the urban grid system across the country since introduction in 1995 with their excellent operating performance.

RVAC RMU’s are characterized by the following:

• Insulation using SF6 gas

• Three position SF6 Switch as the breaking device in the load switch unit to break rated current

• Vacuum arc-extinguishing chamber as the breaking device in the circuit breaker unit to break short-circuit current.

Based on the design principles of all insulation and omniseal, all primary parts of a RVAC RMU are fully enclosed in the SS main case, free from condensation and foreign materials. The main case has the protection grade of IP67 and is equipped with Cooper touchable waterproof cable joints to protect against occasional floods in flood-prone areas

Currently, the development of a grid system is focused on application of ecological resources, requiring a medium-voltage switchgear which is characterised by energy conservation, low operating cost, reliable performance and flexible configuration.

Featuring long service life, compact structure and reusability, the RVAC RMUs have become a role model economically and ecologically. With rapid development of urbanisation, the improvement and perfection of buried cable system has loomed large in terms of equipment and many other aspects. Ring main units (RMU), as the main equipment for protection and sectional isolation of the buried cable system, have been widely used in the urban grid system with their safe and reliable performance, compact and pleasant appearance, and outstanding cost performance.

As the leader in the distribution switch gear field, Eaton Cooper Power Systems (ECPS) started design and production of high-quality distribution switchgears as early as 1942, with over 2,000,000 switchgears in proper operation throughout the world up to now.

RVAC ring main unit construction features


65

Main construction

The load break switch is a 3-position switch (close, open and earthing positions). When in ‘open’ position, the moving blade has sufficient insulation distance. An operating handle can be used to make close-open operations on load break switch, and earthing switch. There are also mechanical interlocks between the load break switch and the earthing switch.

Load break switch

• The load break switch applies metal deionizing arc suppress technology, ensuring good interruption performance for the switch

• The working speed of switch’s moving contact depends on its operation mechanism. The open-close speed of the switch will not be influenced by operators

• When moving from closing to opening, the load break switch will depend on moving contact speed and arc suppress devices simultaneously (to suppress arc and break current)

• The spring operation mechanism with an operating handle is used to complete closing and opening operations. A motorisation module and opening coil can be added to achieve remote control

Product featuresRVAC are human-oriented distribution products developed with advanced R&D technologies and resources, characterised by compact structure, reliable performance, flexible configuration, economy, environmental-friendliness.

The capacitive voltage detection system is used to validate whether the power is safely isolated or not. Various cabinets for RVAC series are equipped with the standard three-phase capacitive voltage detection system to detect potential of circuits. The potential indictor detects effectively whether the circuit is live or not for operators.

Logic mechanical and electrical interlock preventing mal-operationIn RVAC design, different interlocks are adopted to prevent mal-operation of operators. The interlock includes mechanical interlock and electrical interlock. For example, electrical interlock and mechanical interlock can prevent operation of the disconnector when the breaker is switched on. All mechanical interlocks adopt effective direct locking.

The switch can be operated to power supply position only when the door of cable chamber is closed. The door of cable chamber can be opened only when the switch is at the grounding position. The grounding switch can be switched off only when the door of cable chamber is completely closed. The master switch can be closed only when the grounding switch is opened to supply power.

Enclosed cases to keep out foreign materials. In RVAC design, it is impossible that operators or tools unintentional entering the cabinets.

Human-oriented design.The design of all compartments in RVAC cabinet is based on the concept of safe touch from the outside. With human-oriented design, operators will not be injured by motion parts or protruding parts when operating the panel.

Delivery test.RUMs are subject to strict process test and delivery test in accordance with relevant regulations. For quality assurance, all production processes conform to ISO9001. This means relevant components, switches and current transformer will be tested at each production phase to confirm their conformance. After the equipment is assembled as a piece, appearance inspection, mechanical, functional and electrical test will be conducted for the complete set.

Concept of internal Arc preventionEaton has always been committed to production of safe switchgear for operators. For operators, the biggest potential risk is internal arc inside the switchgear. Therefore, the designers employ all necessary methods to prevent internal arc in design of the product.

As required under GB3906, Eaton believes avoiding occurrence of arc is best, instead of protection against it. In the RVAC design, double prevention is implemented.

The RVAC design adopts the structure for which arcs are internally prevented. In case of internal arc, pressure from this internal arc may be relived through the special refeilf channel design for the RVAC to ensure safety of operators to the largest extent, with failure scope controlled as far as possible to minimise damages to other compartments.

Sulfur Hexafluoride (SF6) gasThe insulating and arc quenching medium -SF6

SF6 gas, previously used in circuit breakers with higher voltage levels and with successful achievements, is now in recent years, being used in medium voltage load switching systems.This change happened to systems all over the world, each insulation and arc-extinguishing medium, including air, oil and solid material, has its own critical defect:

• Air insulation systems occupie a large amount of space, which requires maintenance in extreme climates and environments;

• Oil insulation systems can cause huge safety risks due to internal faults, although not influenced by external environment;

• Solid systems have the same maintenance issues as air insulated devices, but with problems at a higher level due to its compact structure.

SF6 is a non-toxic, inert and electronegative gas, heavier than air, offering very effective arc-extinguishing performance, along with the above mentioned high insulation capability. In the case of high temperature arc, produced by circuit breakers, the SF6 gas will resolve into subfluorides. After cooling down, these active subfluorides will quickly return back to SF6 gas. Therefore SF6 gas, which is used under sealing for a long time, will not decrease or deteriorate although under the effect of arc extinguishing several times.

The amount of arc decomposition depends on the water content contained in the SF6 gas. It is very critical to control water content below specified values. Adsorbing agents such as activated alumina/activated carbon and synthetic zeolite remove water and arcing products, which means the volume of the gas originally introduced stays unchanged and can satisfy requirements for working life of the whole system. An evaluation of advantage and potential risks shows that at present there is no substitutable solution of technical and ecological values.

SF6 gas has very high dielectric strength as an insulation medium, thus making very compact products in the design of the structural arrangement maintenance free, since all live parts are completely sealed.

Main performance and characteristics

Flexible solutions• Reliable busbar extended design and interfaces reservered for future project expansion

• Complete types of functional units1. SF6 gas shall be inhibited to emit into air during the process of installation, maintenance and scrapping of devices. Environmental solutions can be used to dispose of SF6 gas which can’t be recycled or reused, which produce natural product gypsum (CaSO4) and fluorite (CaF2).

2. Fore more details, refer to IEC’s technical report 1634 (1995): High Voltage Switchgear and Controlgear - Usage and Disposal of SF6 in High Voltage Switchgear and Controlgear Devices, Chapter 6.5: “Disposal of SF6 at life end- refilling devices.”

The insulating and arc quenching medium -SF6 SF6 gas has been successfully applied in relative HV circuit breakers, and has been increasingly used in the MV load switch system in recent years. This is a global phenomenon. The media previously used for insulation and arc extinguishing (air, oil and solids) has critical defects as follows:

• The air insulation system occupies large space and needs to be maintained at extreme weather or ambient conditions

• The oil insulation system is free from influence of ambient conditions, but will cause high safety risks in case of internal failure

• The solid insulation system needs to be maintained, much like the air insulation system. However, the maintenance proves to be more difficult due to its compact structure.

SF6 gas is non-toxic, inert, and heavier than air in electronegativity. In addition to insulation, it has outstanding arc-extinguishing capability. When high-temperature arc occurs due to circuit breaking, SF6 gas will decompose into sub-fluorides. After cooling, these active sub-fluorides will turn to SF6 gas swiftly. As a result, enclosed SF6 gas will not decrease or deteriorate after numerous arc extinguishing in long-term use. The amount of arc decomposer is relevant to moisture contained in SF6 gas. Therefore, it is very important to keep water content under specified alue.

Absorbents such as activated aluminum oxide, activated carbon or synthetic zeolite are commonly used to remove water and arc decomposer. This means the initial volume of gas that was introduced serves as the operating mechanism throughout its entire service life. When insulation alternatives are assessed on advantages and potential risks there is yet to be a more suitable solution than SF6 when considering technical and ecological factors.
